Physics Notes for Class 11

Physics is a very important branch of science and can be used to solve various problems of mankind.

There are various topics in class 11 physics like kinematics, laws of motion, gravitation, work, energy and power and so on.

The laws of motion were by the great English scientist Newton. These are also known as Newton’s laws of motion.

These three laws are important as they are the foundation for the classical mechanics.

The problems in classical mechanics are solved with the help of these laws.

Gravitation is yet another important topic in class 11 physics.

It basically deals with Kepler’s laws of planetary motion. Gravitation can be also known as gravity.

This is a force which attracts the bodies towards the surface of the earth due to their mass.

There are nearly four fundamental interactions in nature and gravitation is one among them.

The concept of Friction is also taught in class 11 physics and is very important.

Friction is also a kind of force that exists in nature. But this is resistive in nature.

The road offers this to the tyre of the vehicles when they move on the road.

This is one of the several examples that can be given of the frictional force.

Gas is one of the states of matter and its description is given by the kinetic theory of gases. Basically this theory mentions it to be combination of small particles or atoms. The free physics notes for class 11 can be obtained from various sites on the internet.

There are various topics like heat transfer and elasticity which form very important part of the courses like mechanical engineering.

These topics provide the basics that are later needed when one opts for a professional course.

The free physics notes for class 11 can be useful for preparing for the examination as well. The notes can be taken on a Word-Pad or a Microsoft office word document.

Before one starts to learn from the free physics notes for class 11 from various sources one must try to understand the authenticity of the notes.

If the notes are not authentic, there can be error in the concepts. This will lead to solving the problems in a wrong manner.

It is very important to be aware of the concepts and only then they can be applied effectively while solving the problems.

Physics is a subject where concepts play a very important role.

There can be online books also present on the subject. They can also be utilised effectively.

They can help in saving lot of costs for the students. This is the power of internet is realised where many open or free sources are available.

This is not the case only for the notes for physics but for other subjects as well. They will be available on various subjects but one must first search for genuine sites and only then use them.

This is because now-a-days a lot of fake sites and fake information are available.

This is the era of information overload.

So, one must be able to differentiate between genuine and fake information. This capability will help a person or a student to a great extent.

This capability can make a difference on the long run.

The use of fake materials will lead to the learning of wrong concepts and hence in the wrong application of these concepts.

Once the concepts are wrongly applied the solution to the problems can be wrong.

Once the problems are wrongly solved the whole concept of free notes goes for a toss.

The free notes is a great feature and must be used effectively in order to reap rich benefits.

Physics First

Physics First is an educational program that teaches a basic physics course in the ninth grade (usually 15-year-olds), rather than the biology course which is more standard in public schools. This course relies on the limited math skills that the students have from pre-algebra and algebra I. With these skills students study simple kinematics, free fall, Newton's laws of motion, Newton's law of gravity, momentum, experimental analysis and qualitative descriptions of parabolic motion, simple machines (e.g. the lever, gears, pulley), kinetic energy and potential energy, power and work, an introduction to direct current electricity and simple electrical circuits, magnetism, wave motion (mostly hands-on and experimental and qualitative, very little math), the nature of the electromagnetic spectrum.

It began as an organized movement among educators around 1990, and has been slowly catching on throughout the United States. The most prominent movement championing Physics First is Leon Lederman's ARISE (American Renaissance in Science Education).

Many proponents of Physics First argue that turning this order around lays the foundations for better understanding of chemistry, which in turn will lead to more comprehension of biology. Due to the tangible nature of most introductory physics experiments, Physics First also lends itself well to an introduction to inquiry-based science education, where students are encouraged to probe the workings of the world in which they live.

The majority of high schools which have implemented "physics first" do so by way of offering two separate classes, at two separate levels: simple physics concepts in 9th grade, followed by more advanced physics courses in 11th or 12th grade. In schools with this curriculum, nearly all 9th grade students take a "Physical Science", or "Introduction to Physics Concepts" course. These courses focus on concepts that can be studied with skills from pre-algebra and algebra I. With these ideas in place, students then can be exposed to ideas with more physics related content in chemistry, and other science electives. After this, students are then encouraged to take an 11th or 12th grade course in Physics, which does use more advanced math, including vectors, geometry, and more involved algebra.

There is a large overlap between the Physics First movement, and the movement towards teaching conceptual physics - teaching physics in a way that emphasizes a strong understanding of physical principles over problem-solving ability. Many Physics First programs use the popular textbook "Conceptual Physics" by Paul G. Hewitt or "Physics, A First Course" by Tom Hsu.

Criticism

American public schools traditionally teach biology in the first year of high school, chemistry in the second, and physics in the third. The belief is that this order is more accessible, largely because biology can be taught with less mathematics, and will do the most toward providing some scientific literacy for the largest number of students.

In addition, many scientists and educators argue that freshmen do not have an adequate background in mathematics to be able to fully comprehend a complete physics curriculum, and that therefore quality of a physics education is lost. While physics requires knowledge of vectors and some basic trigonometry, many students in the Physics First program take the course in conjunction with Geometry. They suggest that instead students first take biology and chemistry which are less mathematics-intensive so that by the time they are in their junior year, students will be advanced enough in mathematics with either an Algebra 2 or pre-calculus education to be able to fully grasp the concepts presented in physics. Some argue this even further, saying that at least calculus should be a prerequisite for physics.

Others point out that, for example, secondary school students will never study the advanced physics that underlies chemistry in the first place. â€œ[I]nclined planes (frictionless or not) didn't come up in ... high school chemistry class ... and the same can be said for some of the chemistry that really makes sense of biological phenomena.â€� For physics to be relevant to a chemistry course, students have to develop a truly fundamental understanding of the concepts of energy, force, and matter, beyond the context of specific applications like the inclined plane.

Question:including all work, notes, tests, which one would most likely take up more space?

Answers:I think physics will take up more space because I took biology last year and I didn't get that much notes. I never took physics but now I am taking chemistry and it is similar to physics, and I have more notes in chemistry than biology.

Question:I have an 11 year old who is very smart for her age and would like to take college classes at home during her free time. Can she take them for free on the internet.

Answers:1) You can't take free college courses online or anywhere else without getting a scholarship. Even a lot of the ones you have to pay for are scams and not actually worth college credit.
2) Smart for an 11-year old doesn't mean 'ready for college'. Has she taken pre-calculus? Most college students will start college taking calculus-based courses. Is she writing and reading at a college level? Has she taken high-school-level bio, chem, and physics classes?
3) You have to send all previous college transcripts to the college you eventually want to attend - even those you failed. And that doesn't look good.
